ROOKFORD, ILLINOIS, A CORPORATION DELAWARE PEG Application led May 7,1927. Serial No. 189,528.

, This invention relates to pegs in general and more particularly toshelf pegs of the type used to support the shelves or trays inrefrigerators and aims to improve generally I on such pegs.

The pegs heretofore customarily used for supporting refrigerator shelveshave been threaded at their outer end and provided adjacent the innerend of the threaded portion with a circumferential shoulder adapted whenthe threaded portion of the peg Was projected through an opening in therefrigerator lining to abut against the inner surface of the liningwhich was clamped between this shoulder and a nut thr'eaded onto theprojecting outer end of the peg. These pegs Were mounted or attached tothe lining prior to its assembly in the refrigerator cabinet. Theclamping nuts being disposed on the outside of the lining were, when thelining was in position in the cabinet, entirely .inaccessible With theresult that if they became loose in use, they could not be tightened upagain and not infrequently, they dropped ofi' entirely so that the pegbecalne useless.

It is accordingly the principle object of this invention to provide ashelf peg capable of being used in connection With refrigerators or thelike in which the nut is disposed on the inside of the lining Where itis accessible and can be tightened at any time should it become looseafter assembly of the refrigerator.

Itis also an object of this invention to pro-v vide a peg of this typewhich may be-replaced from the inside of the lining or other support towhich it is adapted to be attached.

Other and further objects of this invention will be apparent as the samebecomes better understood from an examination of the specification andclaims in connection with the accompanying drawings wherein,

Fig. 1 is a fragmentary sectional View showing the v vall of arefrigerator provided with a lining having attached thereto a shelf pegembodylng this invention.

Fig. 2 is a sectional view taken at the line- 2 2 of Fig. 1.

Fig. 3 is a perspective view of the shelf peg With parts omitted.-

Fig. 4 is a fragmentary elevational view taken from the outside of therefrigerator compartment lining, a modified shelf peg attached theretoembodying this invention.

Fig. 5 is a perspective View of the modified shelf peg with partsomitted.

Referring to the drawings more particularly, numeral 6 represents theouter shell of a refrigerator Wall having suitable insulation 7 and asheet metal lining 8 spaced therefrom to provide an air space 9.

The lining 8 is provided with a rectangular or other shaped aperture asat 11 to receive a shelf peg represented generally by the number 10.

Pegs 10 arefpreferably made by taking sections of wire upsetting them atone end to provide an integral head 12 and an enlarged portion along theshank in proximity to said hea-d on which portion are subsequentlyformed the threads 13 and a rectangular'or other shaped portion 14 onthe inner side of said head and corresponding to the shape of theaperture 11. The rectangular portion i4: cooperates With the aperture 11to hold the peg against any rotational movement' tending -to Work thepeg loose and also facilitates assembly by holding the peg againstrotation While tightening the nut which will be hereinafter described.the peg is bent to form the hook portion 15 on a radius permitting thespringwvasher '17 and also the nut 16 to be slipped onto the peg overthe hooked end thereof.

The nut 16 is threaded on the threads 13 for clamping the edges of thelining 8 adjacent the aperture 11 against the head 12, a convex springWasher 17 preferably being used between said nut and lining to preventThe inner end of the nut from Working loose and to form an openingthrough which e the shank passes.

air tight seal around the geg In the process of assem ly, the peg isinserted from the outside of the linlng 8 and is -attached theretobefore the lining is secured in lace in the refrigerator. In the pegsusedp heretofore, a threaded nut was used in place of the head 12 and ashoulder was provided on the peg whichcooperated with said nut forclamping the peg to the lining, the nut being left-on the outside of thelining so that it was inaccessible after assembly and should the nutbecome loose,- it could not be retightened and it might even drop ofi'and fall down in the space 9. When my peg is used, the nut 16 can notpossibly drop oi but should it become loose, it can readily' betightened again, because it is on the near side of the lining 8 andaccessible at all times.

' In Figs. 4 and 5, there is shown a modification in which the lining 8is provided with a horizontally elongated 'aperture 18 in place oftheaperture 11 and the peg is provided with an elongated head 19 m placeof the round head 12 so that the peg can even be l installed from theinside of the refrigerator after the linin 8 has been secured in place.In installing tlgie peg, the elongated head 19 is inserted through theaperture 18 and the peg is then given a ninety degree turn. The nut' isthen tightened as in the previous embodiment. When this modifiedconstruction is used, the entire peg may be renewed after therefrigerator has been completed.

I am aware that many details may be varied throughout a wide rangewithout departing from the principles of this invention and I thereforedo not wish to be limited t0 the details shown ordescribed.

I claim:

1. The combination with a refrigerator wall having an enameled surface,of a shelf peg having a shank extending through an opening in the yWalland provided with a head engaging one face of the wall, a nut threadedupon the shank, and a sealing device located between the nut and theenameled surface of the wall and provided with centrally 1ocated meansto engage the nut and space it` from the enamel surface, said sealingdevice also provided with peripheral means engaging the enamel surfaceremote from the edge o f the opening to seal the opening and preventcracking of the enamel around the edges of the opening.

2. A shelf peg for refrigerator walls and the like,` comprising a shankhaving one end portion provided with a head, the shank being screwthreaded adjacent the head, a nut on the screw threaded portion of theshank', and a resilient sheet metal sealing device slidable upon theshank between the nut and the head and provided with a central boss orcifset for contact with the nut and to span the nature.
